I was there 6 months ago and it is more than what the video shows. You just have to be there, like the Grand Canyon.
I also visited a bunch of other MRR shops in Tokyo, Kyoto and Osaka. If you every visit, your mind will be blown. The Japanese are very serious about their N-scale trains. Oh, prices are 40-60% cheaper than US prices and you get a full selection of Tomix, which is pretty much non-existent in the US (thank you Walthers!
).
